Blower Door Test in Totowa, NJ

How Is A Blower Door Test Conducted?

While performing blower door test in Totowa, NJ, technicians make sure exterior doors and windows are shut tight and interior doors are open for uniform pressure. A central door to the outside is selected, and an adjustable aluminum frame with a fabric cover is installed there. A calibrated fan is fitted into the frame and depressurizes the home to 50 Pascals, mimicking the pressure caused by a 20 mph wind.

As the fan creates negative pressure, outside air infiltrates the home through gaps and small openings. A nanometer precisely gauges the pressure applied by the fan in relation to the home’s internal air pressure. The data collected is translated into air changes per hour (ACH), showing the home’s airtightness and overall energy efficiency in NJ conditions.

What Is A Passing Blower Door Test Score?

In Totowa, NJ, residential buildings must meet the benchmarks set by the 2015 International Energy Conservation Code (IECC) or any newer codes adopted locally. Typically, blower door test compliance means maintaining 3 air changes per hour or less for energy-efficient performance. Reaching the target during your blower door test in Totowa, NJ guarantees lower energy consumption and full code compliance.
